Verizon Business Fiber: Fios, Dedicated Internet Access and Ethernet Over Fiber

Verizon Business Fiber spans three products built on the same Verizon fiber plant but sized for different operational needs. Fios Business Fiber covers the single-site, gigabit-class office. Dedicated Internet Access carries headquarters and data-centre traffic with legally binding SLAs. Ethernet over fiber links two Verizon-served addresses at layer 2, bypassing the public internet.

Every fiber circuit lives inside My Verizon Business next to the wireless roster and One Talk voice lines, so the operations team sees a single view for uptime, ticket history and throughput. Support phone routing at 1-800-465-4054 recognises fiber circuits and hands the call to a business-wireline engineer within two rings.

Dedicated Internet Access (DIA) sells bandwidth, not best-effort capacity. The fiber pair is dedicated to one customer, the ethernet handoff is symmetric, and the service level agreement commits to specific numbers for round-trip latency, jitter and packet loss. Miss the target and the contract pays financial credits automatically.

Bandwidth tiers scale from 100 Mbps up to 10 Gbps. Regulated industries pick DIA for the audit-ready SLA paperwork; the Federal Reserve supervisory letters on operational resilience are a common reference when banks size WAN capacity. The NIST Cybersecurity Framework also cites availability commitments as a core control.

Ethernet over fiber (EoF) is point-to-point. Two Verizon-served addresses — for example headquarters and a data centre — get a dedicated fiber circuit that behaves like a very long ethernet cable. EoF supports VLAN trunking, jumbo frames and ISP-independent routing. Replication jobs, backup windows and inter-building voice trunks run on EoF without competing with internet traffic.

EoF typically pairs with DIA or Fios Business Fiber for separate internet egress. The combination — EoF for private traffic, fiber broadband for internet — gives a clean separation that SD-WAN controllers and firewalls can police on their own rule sets. Tier sizes run 10 Mbps to 10 Gbps.

Standard SLA on Fios Business Fiber targets 99% monthly uptime with best-effort repair. It is adequate for non-critical branch offices and retail back-of-house operations where a brief outage is tolerable. Enhanced SLA steps up to 99.9% monthly uptime with documented MTTR windows and explicit trouble-ticket escalation paths; this tier suits clinics, pharmacies and branch banks that cannot operate without connectivity during business hours.

DIA carries the strictest SLA: 99.99% monthly uptime, four-hour MTTR, latency and jitter thresholds measured with quarterly reports, and financial credits that trigger automatically when commitments are missed. Headquarters sites, trading floors and card-processing data centres almost always run DIA because the SLA language is what the auditors want to see.
